WHAT IS THIS PART CALLED?

Lexus Other

Long story short. Got my 95 Lexus ES300 stuck in a driveway & when being towed out the guy hooked to some type of rod or bar apprx 1 foot long underneath the front of car, Just below where your front tag would be. The rod is metal and has fins on each side of it. When it broke lose, transmission fluid came out. What is this thing called. And yes, I am a women!
